从PHP或CURL中的链接读取Excel文件

I have a client project in which I have to read an excel file from following link:
https://app6.bosch.de/cgi-bin/WebObjects.dll/V5Prod_WES6.woa/39/wo/UpG9CtiiPkkyvA2ECwgqkg/41.0.1.3.21.1.1.9.9.0.2.27.3.17.7.1

Everytime a new link is generated, when we click on this link in normal site, it opens in a new tab an excel download option.

How to read the same file from my website using PHP (e.g. using curl)? I want to read this file and save it in my website directory automatically.
